当我运行"Ionic start project name"时,我总是收到此错误消息:

错误信息

Running command - failed![ERROR] An error occurred while running npm install (exit code 1):

        throw err;
        ^

我试图使用PolymorphicJsonAdapterFactory以获得不同的类型，但总是遇到奇怪的异常：

缺少 test_type 的标签

我的实体：

@JsonClass(generateAdapter = true)
data class TestResult(
    @Json(name = "test_type") val testType: TestType,
    ...
    @Json(name = "session") val session: Session,
    ...
)

这是我的莫西工厂：

val moshiFactory = Moshi.Builder()
    .add(
        PolymorphicJsonAdapterFactory.of(Session::class.java, "test_type")
            .withSubtype(FirstSession::class.java, "first")
            .withSubtype(SecondSession::class.java, "second")
    )
    .build()

json响应的结构：

 {
   response: [ 
      test_type: "first",
      ...
   ]
}
